Stars Who Have Seen Ghosts

Lady Gaga

In May 2010, the Mirror reported that Lady Gaga spent £3,000 on electromagnetic field sweepers and other equipment to remove evil spirits and "bad energy" before her Monster's Ball concert in London. "Her aide said the gear had to be robust as they were—taking it on the road," the owner of the ghost-busting gear told the paper, "so they must be doing this everywhere Lady Gaga is performing." Several months later, Gaga still felt spooked and held a séance to scare away the ghost, whose name is reportedly Ryan. As a source from her tour explained: "She's pretty terrified by this spirit, but more than anything he's annoying her as he won't leave her alone. He hasn't been doing anything too violent or scary, but she's freaked out by his presence."

In an episode of Celebrity Ghost Stories, designer Cynthia Rowley recalled a terrifying encounter with a spirit after moving into "the perfect, idyllic country house" in Greenwich, Connecticut. The chic spook always wore a gray head scarf so Rowley couldn't quite see her face. Then one Christmas, after Rowley hung a giant wreath above her fireplace, her husband warned her not to light the candles on the mantel. "I don't know what came over me," Rowley said, recounting how she lit the candles right before a holiday party. "Something made me do it." The second she struck the match, the flame jumped to the wreath and the room caught fire. Rowley escaped the flames, but when the firefighters arrived, they looked a little spooked. "You know who used to own the house?" one fireman asked Rowley. "The woman that built the house...was the heiress to the Diamond Match fortune...who was badly burned and disfigured in a fire in her father's match factory as a teenager." The haunted mansion is currently for sale with an asking price of $39 million.
